Thank you so much! I have an exam tomorrow about this and now I'm confident to pass it. Yours was so much more understandable and clear than the teachings and notes in my class.
i never comment on youtube videos but i was stuck for like two hours trying to teach myself how to do this and you did it in eleven minutes... i hope you understand my immense gratitude your students are so lucky to have you thank you
I was so confused on how to do this before, our teacher recommended this video just in case and you literally saved me you made it so easy to understand thank you so much!
i love this way of taking notes where you only write things down without gluing down 15 pages every day, you seem like a good algebra teacher (unlike mine)
thank you , so much . you are a genious . my math teacher explained it in a really complicated way by using a calculator something called '' MODE 5'' thank you soooo much . I love you
AHHHHHHHH here in 2019 with a test on this tomorrow, been searching RU-vid for HOURS for a video on this but this is literally the only one that made sense THANK YOU SOOOO MUCH!!!!
Thank you so much for making this video! I myself am autistic and I have a hard time understanding math or certain ways it’s laid out for me. This really helped me out!! Thanks again :)
Well done. This is a nice video on how to write the quadratic polynomial if you are given the table first, rather than generating a table by evaluating the polynomial over a set of integer inputs. I send out this link to students who need extra help or if they missed my live instruction. The only thing I have to tell them is near the end, the lower case a will look like a two in the video. :-)
THANK YOUUU,, i'm currently homeschool right now due to the pandemic (my school said they might send us to school if things calm down and my parents weren't having it) and i literally have no one to help me. thank you for teaching me :DD
Thank you so much. My teacher has taken a term to try and explain this and everybody is still confused, at least I know what I am doing now. THANK YOU SO MUCH!
Oh my gosh I think I'm in heaven this was exactly what I needed thank you so much mysterious math lady, I hope you go on to bless another soul of the damned with your knowledge
Thank you so much I recently joined advanced math and I am a 8th grader I did not do 8th grade math instead I did 9th grade math I was have a very hard time thank you really this means alot :D
thank you so much!! I have a question, while solving the same problem, you said that we can choose any value for c so I chose 1,5 and for the x y values I chose 3, 7 so in the end, I got y=x^2+15x+5. Is it correct?
Hello! I'm not sure what you mean when you say more than one 0 term - if there are two different y values for one x value then the relation is no longer a function (meaning it cannot be quadratic).
You can use a pattern with the second difference to work backwards towards it OR you can create a system of equations using any two points rather than c and you can solve for b & c that way. It is a bit more complicated but still works!
